This invention is 'particularly designed to supply saline solutions tor hospital use. -ln the use ot' such asolution it is desirable to have a solutionoif preLd-etermined strength which may be readily stored in concentrate form, diluted in measured quantities with the predetermined vstrength and delivered conveniently ifor use in an assured sterile condition. Features and details of 4the invention will appear from the specification and claims.

The invention is illustratedin the accompanying drawings as vfollows 2- Fig. 1 shows'a section on the line 41 1 -in Fig. 2. e

`1 marks the stand on which Athe apparatus is mounted, .2 a storage tank, this being ot' ordinary form for storing and maintaining sterile distilled water. 3 a steam ypipe connection Aleading to the storage tank and 'to the dispensing apparatus bv which it may be sterilized, and l a connection leading vtrom the storage-tank to the body 5 ot the measuring valve.

The `measuring valve Vhas a tapered valve opening 6 through itin which a measuring valve T ismounted, the measuring valve `being in the form of an ordinary plug valve except that it Ilias a measuring chamber. lt is provided -ivith a handle 8 at one end, a screw-threaded extension 9 at the opposite end, and a spring- 10 arrangedaronnd the extension `9 and between a Washer 11 and nuts 12, the spring being designed to maintain themeasuringvalve on its seat. Y

flllhevmeasuring :valve vbody ihasa rport `13 .which lis connected'by avpip'e 14 fvvith a 'mixing chamber 15. lt is also provided vvitha port 16 connected by a pipe y17 Withaconcentrate containing receptacle 18. Thebo'dy also has a port 19 which is connected by a pipe 20 with the pipe 3, the -pip'e'20 vbeing also connected through 'pipe 21 nvit'h the upper end of the receptacle 18. The body also has a discharge nort`22 which -leadstoA a discharge nozzle 22"-. rEhe valve 'i7 Ihas a measuring chamber 23 `which lholds a predetermined 'amount of concentrate. A vvay 24 leads from this chamber and is adapted to be brought into register With the lport '16. llt also has a Way 25 which 'is adapted "to be brought'into register Yivith the port j19'at the same time the port ,24 is in register 'Withthe port 16. lfihen itis desired to lill the measuring chamberof 'the measuring valve With concentrated solution the valve is moved to the position shoivninFig. 3 and concentrated solution passes by Way of the pipe 17, port 1G, way 24 tothe mixing chamber. Any air inthe measuring chamber is allowed'to'escape by `Way of the vvvay,port 19, and the pipe 20 so that the lilling of the measuring chamber is assured. This position of the valve is indicatedon-thedial 29, the pointer 30 being brouglitto `the place markeduSalt. Thevalvejis then turned to the position shown in Fig. 5. A Way 26 i-s arranged 'in' the valve plug and this is adapted to be brought into Kregister' `with the port I13. It is also provided `with away 27 vvl'iichjis adapted to be 'brought into register )vith a. port- 25' (see dotted lines) to vvhich'the pipe is connected. Diluting liquid, therefore, passes immediately from the storage'tank 2, cro-vvding the 'concentrate solution before `it and clearing' the ent-ire solution from the chamber 23 and filling the mixingchamber 15. The mixing chamber is provided Witha valve B1 at its upper end Vwhich isyoontrolle'd bv a float 32 so that when the mixing chamberthas been iilled Ifrom the storage tank With the diluting liquid and the measured concentrate itis closed. o

yThe valve is then vmoved to the position shown in Fig. 7. The valve has a Way 28 Which-is adapted to be brought into register with the port 13 at the same time 'that the way 9a in the valve is brought into register with the discharge port 22 and the measured diluted saline solution then drains from the mixing chamber past the measuring valve through the discharge nozzle to the receptacle from which it is used. The valve is then closed by turning it to the position shown in Fig. 9 where all the ports and ways are out of register. The dial 29 acting in connection with the pointer 30 gives the position of the valve in each instance, thatis to say, with the position shown in Fig. 5 the dial indicates that the valve is in mixing position. With the position shown in Fig. 7 the dial indicates that the valve is in position to draw, and with the parts in the position shown in Fig. 9 the dial indicates that the valve is closed.

By opening the valve 33 in the steam pipe 3 steam may be blown through the measuring' valve, pipe 20, 2l, receptacle 18 and mixing chamber, and in fact all the connections so that they may be thoroughly sterilized. 'Ihe concentrate solution is put into the receptacle 18 by removing the cap 34. This cap is pro-- vided with a check valve 35 which assures the sterilizing pressure on the chamber. This cap has a sterilizing gauze 36 which admits sterilized air as the concentrate is withdrawn.
